The  Concrete  Chuting  Plant 


A  CHUTING  plant  may  be  used  in 
two  ways,  it  may  be  designed  to 
deliver  the  concrete  to  floor  hoppers  at 
centralized  points  on  the  work,  or  the 
plant  can  be  laid  out  for  pouring  direct 
into  the  forms.  To  determine  which 
method  should  be  used  requires  a  study 
of  each  particular  job. 

Types  of  Plants 

There  are  three  types  of  chuting  plants 
in  use.  First,  the  Boom  Plant;  second,  the 
Unit  Plant;  third,  the  Continuous  Line 
Plant.  Of  course,  there  are  various  pos¬ 
sible  combinations  of  the  three  types,  but 
as  a  general  rule  boom  and  unit  plants 
apply  almost  entirely  to  building  work 
and  the  continuous  line  plant  to  dams, 
bridges  and  work  of  that  character.  The 
various  types  of  plants  are  illustrated  on 
the  opposite  page. 

Advantages  of  the  Chuting  Plant 

In  general,  a  chuting  plant  consists  of  an 
elevator  bucket,  which  operates  in  a  tower 
and  a  tower  hopper,  which  may  or  may  not 
be  mounted  on  a  sliding  frame  and  the 
necessary  chutes  for  covering  the  job.  A 
properly  laid  out  chuting  plant  should 
produce  a  marked  saving  in  time  and 
labor.  The  amount  of  concrete  which 
can  be  placed  is  limited  only  to  the  capac¬ 
ity  of  the  mixing  plant  and  the  forms 
available.  The  point  of  pouring  can  easily 
be  diverted  from  point  to  point  without 


it  being  necessary  to  take  up  and  replace 
runways.  More  continuous  operation  of 
the  mixing  plant  will  be  secured  which 
naturally  means  more  economical  opera¬ 
tion.  Or  again  due  to  local  conditions,  it 
may  be  impossible  to  locate  the  mixing 
plant  exactly  at  the  building  or  perhaps 
the  concrete  has  to  be  carried  over  a 
stream  or  other  obstruction.  On  such 
jobs,  the  chuting  plant  provides  a  method 
for  solving  the  problem  economically. 

Is  Not  a  One  Job  Installation 

The  chuting  plant  can  no  longer  be 
considered  a  one  job  installation.  It  is 
durable  and  easy  to  move — it  is  com¬ 
posed  of  standard,  interchangeable  parts 
which  can  be  fitted  and  rearranged  to 
meet  practically  any  job  requirement. 
The  interchangeability  of  the  various 
units  also  means  quicker  and  easier  erec¬ 
tion.  The  Chuting  Plant  is  really  a  ma¬ 
chine  and  to  secure  the  results  desired, 
must  be  correctly  applied  to  the  work  at 
hand  and  properly  operated. 

The  Lakewood  Engineering  Company 
is  one  of  the  pioneers  in  the  manufacture 
of  concrete  chuting  equipment  and  today 
Lakewood  Equipment  is  recognized  as  a 
standard  thruout  the  world.  The  exper¬ 
ience  of  Lakewood  engineers  with  chut¬ 
ing  plants  covers  practically  all  types  of 
concrete  construction.  They  will  be  glad 
to  cooperate  in  any  way  possible  on  lay¬ 
out  work  and  such  cooperation  involves 
no  obligation  upon  those  requesting  it.

Boom  Plant 

On  the  boom  type  of  plant  the  peaking  line 
connection  and  steel  boom  seat  are  all  mounted 
on  a  steel  sliding  frame  with  the  tower  hopper. 
The  first  section  of  chute  runs  through  an  open¬ 
ing  in  the  boom  and  does  not  require  trussing. 
This  type  of  plant  is  used  principally  with  Coun¬ 
terweight  chutes  on  either  wood  or  steel  towers. 
This  plant  is  owned  by  the  Hunkin-Conkey 
Construction  Company,  Cleveland,  Ohio. 


Unit  Plant 

The  Unit  Plant  combines  the  steel  boom  with  the  first  section 
of  chute.  Altho  this  requires  a  slightly  higher  tower,  the  plant 
is  easy  to  erect  and  simple  to  operate.  When  the  pouring  end 
of  the  second  section  is  moved  the  balance  of  the  plant  finds  its 
own  position.  Counterweights  can  be  used  with  the  Unit  Plant 
as  well  as  with  the  Boom  Plant. 


Continuous  Line  Plant 

The  Continuous  Line  Plant  has  many  varia¬ 
tions.  It  may  be  simply  a  straight  line  of  chute, 
or  line  gates  may  be  installed  at  various  points 
for  distributing  the  concrete  to  points  under  the 
chute  line.  Many  times  an  economical  combina¬ 
tion  is  a  continuous  line  chute  with  a  Counter¬ 
weight  at  the  discharge  end  of  the  line  for  dis¬ 
tributing  the  concrete.  This  Plant  used  by  the

The  Concrete  Chuting  Plant 


Consistency  of  Concrete  for  Chuting 

HE  general  statement  is  sometimes  made 
that  to  chute  concrete,  an  extremely  wet, 
sloppy  mix  is  required.  As  a  matter  of  fact,  a 
very  sloppy  mix  will  cause  continuous  trouble 
with  any  chuting  plant  because  the  mix  separates 
in  the  chute,  the  grout  leaving  the  heavier  aggre¬ 
gates  stranded,  causing  clogging.  Practical  ex¬ 
perience  with  hundreds  of  chuting  plants  has 
proved  that  a  good,  creamy,  workable  mix  is  the 
one  which  can  be  handled  the  easiest  in  a  chut¬ 
ing  plant,  providing  the  proper  slope  for  the 
chute  is  maintained,  and  that  excessively  wet 
batches  or  flat  chute  lines  are  almost  entirely 
responsible  for  difficulties  experienced  with  a 
properly  laid  out  plant.  Concrete  varying  in 
slump  under  the  standard  “slump  test’’  from  3" 
to  6"  can  be  handled  satisfactorily  in  chutes. 

Proper  Slope  for  Chute  Lines 

For  chute  lines  not  over  175  ft.  in  length,  a 
slope  of  not  less  than  one  to  three  is  recommended 
and  on  that  slope,  a  good  concrete  mix  can  be 
handled  satisfactorily  in  all  respects.  On  lines 
longer  than  175  ft.,  we  recommended  a  one  to 
two  and  three-quarters  to  a  one  to  two  and  one- 
quarter  slope,  depending  upon  the  capacity  de¬ 
sired,  the  length  of  the  line,  the  type  of  aggre¬ 
gate  used  and  the  slump  specified.  It  has  been 
demonstrated  that  concrete  much  drier  than 
that  ordinarily  used  on  building  construction 
can  be  placed  with  chutes  on  the  slopes  as  out¬ 
lined  above. 

Relationship  in  Size  of  Buckets, 
Hoppers,  Etc. 

There  is  a  general  rule  covering  the  size  of 
bucket  and  hopper  to  be  used  with  a  given  size 
of  mixer  which,  in  general,  can  be  stated  as 
follows:  The  working  capacity  of  the  elevator 
bucket  should  correspond  with  the  wet  batch 
capacity  of  the  mixer.  The  tower  hopper  should 


have  at  least  fifty  per  cent  greater  working 
capacity  than  the  bucket  to  provide  extra 
storage  capacity  in  case  of  a  hold  up  of  the 
concrete.  All  Lakewood  elevator  buckets  and 
tower  hoppers  are  rated  on  a  conservative  work¬ 
ing  basis  and  have  a  considerably  larger  water 
level  capacity  as  reserve. 

Greater  Capacity  and  Length  of  Life 
with  Lakewood  Chute 

Lakewood  standard  chute  has  a  body  of 
twelve  gauge  plate  and  a  greater  cross  sectional 
area  than  any  other  type.  It  gives  in  addition 
to  its  greater  capacity,  forty  per  cent  more 
wearing  thickness  of  body  than  chutes  made  of 
14  gauge  plate. 

The  thickness  of  chute  reliners  will  depend 
upon  the  yardage,  slope  of  chutes,  and  type  of 
aggregate.  It,  of  course,  is  true  that  12  gauge 
Lakewood  chute  will  not  require  relining  where 
14  gauge  chutes  will. 

Standard  reliners  are  made  of  12  gauge 
and  34"  plate  for  all  sizes  of  chutes.  Reliners 
can  be  bolted  or  riveted  in  place. 

All  Lakewood  Chute  Half  Round 
in  Cross  Section 

Lakewood  chute  of  all  sizes  is  half  round  in 
cross  section.  This  cross  section  gives  the 
maximum  capacity  and  makes  for  easier  flow 
of  the  concrete,  because  it  eliminates  wedging 
action.  The  greater  wedging  action  found  in 
narrow  egg-shaped  chutes  not  only  retards  con¬ 
crete  flow  but  increases  the  wear  at  the  bottom 
of  the  chute  plate.  This  is  particularly  true 
where  large  aggregate  is  used. 

Specifications  calling  for  drier  concrete  again 
emphasize  the  advantages  of  the  half  round 
Lakewood  chute  cross  section.  With  dry  con¬ 
crete,  wedging  action  must  be  reduced  to  a 
minimum  for  easy  handling  and  that  is  secured 
with  Lakewood  chute.

Four  Sizes  of  Chute 

Lakewood  chute  is  made  in  three  general 
types.  First,  14"  diameter  with  arched  cross 
bands  and  second,  18"  diameter  with  arched 
bands.  These  types  are  all  standard  stock  sizes. 
Special  20"  diameter  chutes  and  larger  can  be 
furnished  where  hourly  capacity  and  size  of 
aggregate  require  them.

Cross  Sectional  Area  96. .5  sq.  in. 


Lakewood  18"  Chute  with  Arched  Bands 
Cross  Sectional  Area  171  sq.  in. 


Arch  Band  Chute  An  Original 
Lakewood  Design 

The  use  of  the  arch  band  on  chute  sections, 
a  feature  of  design  now  recognized  as  standard 
for  all  large  jobs,  was  developed  by  Lakewood. 
The  increased  hourly  capacity  desired  and  the 
use  of  aggregate  running  as  large  as  6"  to  8" 
in  chutes  on  dam  construction  were  primarily 
responsible  for  the  development.  On  the  average 
job,  flat  band  chute  will  meet  requirements,  but 
on  large  jobs  where  the  chutes  are  running  full 
continuously,  flat  cross  bands  slow  up  the  flow 
of  the  concrete  and  cause  clogging.  This  is 
particularly  true  with  large  aggregate  concrete. 
Actual  experience  on  jobs  indicates  that  14" 
arch  band  chute  will  easily  handle  15%  to  20% 
more  concrete  per  hour  without  clogging  than 
will  standard  14"  flat  band  chute. 


Capacity  of  Standard  Chute  Sections 

Lakewood  14"  arched  band  chute  will  handle 
all  the  concrete  a  one  yard  mixer  can  mix, 
while  18"  arch  band  chute  has  handled  the 
capacity  output  of  three  two-yard  machines  on 
dam  construction. 


Factors  of  Success 

The  success  of  a  chuting  plant  and  the  satis¬ 
faction  with  results  secured  from  it,  both  from 
the  contractor’s  and  the  engineer’s  standpoint 
are  dependent  upon  certain  definite  things — 
first  of  all,  a  good,  workable,  creamy  mix  of 
concrete,  not  a  sloppy,  extremely  wet  mix. 
Second,  securing  as  nearly  as  practicable,  the 
same  consistency  of  concrete,  batch  after  batch, 
from  the  mixing  plant.  Third,  an  experienced, 
capable  man  regulating  the  flow  of  concrete 
into  the  line  from  the  hopper  and,  fourth,  a 
properly  laid  out  plant.  The  importance  of 
this  last  item  cannot  be  underestimated.

The  Boom  Counterweight  Plant 


The  boom  counterweight  plant  is  the  most 
commonly  used  type  of  chuting  plant. 
Designed  for  use  on  either  steel  or  wood  towers, 
it  provides  a  flexible  and  economical  plant  for 
placing  concrete  within  a  175-ft.  radius  of  the 
supporting  tower. 

A  plant  of  this  type  is  diagramed  completely 
on  pages  22  and  23.  Vertical  flexibility  for  the 
plant  is  obtained  by  mounting  the  boom  and 
tower  hopper  on  a  steel  frame,  which  slides  on 
guides  attached  to  the  outer  sides  of  the  front 
corner  posts  of  the  tower.  This  frame  is  shifted 
by  means  of  a  cable  running  over  sheaves  on  top 
of  the  tower  to  the  hoisting  engine,  and  permits 
moving  the  plant  on  the  tower  as  a  unit. 

Counterweight  Sections  Save  Labor 

The  use  of  a  counterweight  chute  as  the  second 
section  of  the  plant  greatly  reduces  the  time  and 
labor  required  for  moving  the  chutes  from  point 
to  point  when  pouring.  Counterweight  chutes 
are  simply  standard  sections  with  a  truss  so 
arranged  that  a  weight  hung  at  the  end  of  the 
truss  balances  the  chute.  As  Lakewood  counter¬ 
weight  chute  sections  are  made  in  20-ft.,  30-ft., 
and  50-ft.  lengths,  a  great  number  of  plant  com¬ 
binations  are  possible.  Additional  sections  can 
be  attached  to  the  counterweight  section  to  cover 
a  greater  area  if  the  job  requires  it. 

« 

While  the  standard  plant  makes  use  of  a  50' 
boom  many  of  the  plants  illustrated  in  these 


pages  are  equipped  with  75'  and  80'  booms. 
This  increases  the  working  radius  of  the  plant 
proper,  without  chutes  beyond  the  counter¬ 
weight  section,  to  125'  and  130'. 

Many  Combinations  Possible 

Using  a  boom  counterweight  with  a  light  type 
counterweight,  the  discharge  end  of  the  counter¬ 
weight  must  always  be  supported  when  pouring 
concrete.  However,  if  desired,  the  heavy  type 
counterweight  sections  may  be  used  and  the 
counterweight  tied  down  when  pouring  concrete. 
F'urthermore,  the  plant  may  be  extended  by 
additional  30-ft.  length,  in  other  words,  to  130- 
ft.  radius,  and  the  counterweight  may  be  tied 
down  during  concreting,  thus  eliminating  all 
supports  for  the  plant  except  the  discharge  end 
of  the  30-ft.  chute  section.  Many  times  this  is 
a  valuable  feature  on  the  job.  However,  with 
this  type  of  plant,  the  heavy  counterweight  must 
not  be  tied  down  with  more  than  a  30-ft.  chute 
attached,  when  pouring  concrete. 

Plant  Has  Many  Applications 

Altho  the  boom  counterweight  plant  is  used 
principally  on  stationary  towers  alone  or  in  com¬ 
bination  with  continuous  line  chute,  it  has  been 
found  to  be  a  very  valuable  unit  for  use  with 
portable  plants,  mounted  on  cars,  special  travel¬ 
ers,  or  barges;  the  car  plant  is,  of  course,  most 
valuable  on  bridge  work,  grade  separation,  re¬ 
taining  wall  and  steel  mill  foundation  work.

LAKEWOOD  CONCRETE  PLACING  EQUIPMENT 


The  Steel  Tower 

The  fundamental  idea  in  the  design  of  the  new  type  Lakewood  steel  tower  was  to  cut 
down  the  number  of  different  parts  required  for  the  tower,  thus  making  erection  easier 
and  quicker  and,  at  the  same  time,  develop  greater  strength  than  ever  heretofore  secured 
for  standard  equipment. 

This  has  been  accomplished  with  the  result  that  the  new  Lakewood  steel  tower  offers 
greater  strength,  fewer  different  parts,  greater  flexibility,  greater  possibilities  as  to  plant 
layout  and  easier  and  quicker  erection  than  any  tower  on  the  market.  This  statement  can 
be  quickly  proved  by  a  comparison  of  the  following  specifications  covering  the  Lakewood 
steel  tower. 

THE  TOWER  MAKE  UP:  The  standard  tower  is  EVERY  NOSE  BOARD  ALIKE:  A  15-ft.  section  of 


made  up  of  a  top  and  bottom  section  with  as  many 
intermediate  sections  as  desired  for  height.  Each 
intermediate  section  is  15-ft.  high  and  is  divided 
into  two  panels  of  7)^'  each.  The  top  and  bottom 
sections  are  not  figured  as  adding  height  to  the 
tower.  All  intermediate  sections  are  interchange¬ 
able  in  parts  and  position. 

MAXIMUM  HEIGHT:  The  standard  Tower  can 
be  built  to  a  height  of  240-ft.  with  a  130-ft.  boom 
counterweight  plant,  tied  down  when  pouring 
concrete. 

BOLTS:  All  the  bolts  required  for  the  tower  are 
furnished;  bolts  are  used  thruout. 

BOTTOM  SECTION :  The  bottom  section  consists 
of  four  heavy  angles  to  which  are  riveted  34"  plates 
to  provide  perfect  bearing  for  the  tower  without  in¬ 
creasing  the  number  of  shipping  units.  Anchor  bolt 
holes  are  provided  for  in  the  gusset  plates  and  angles 
of  the  bottom  section.  Any  intermediate  section  can 
be  attached  to  this  bottom  section. 

BOTTOM  SHEAVE:  A  16"  bottom  swivel  sheave 
of  heavy  construction  is  furnished  for  the  base  of 
the  tower.  The  support  for  this  sheave  is  so  designed 
that  the  sheave  can  be  put  at  the  very  bottom  of  the 
tower  or  at  the  first  panel  point,  734'  up,  as  condi¬ 
tions  demand.  This  takes  care  of  the  bottom  sheave 
in  case  the  base  of  the  tower  is  put  below  ground 
level.  The  bottom  sheave  support  can  be  placed  on 
either  side  of  the  tower  desired. 

EN’ERY  (JIRT  ALIKE:  The  girts  are  angles.  Every 
girt  on  the  tower  is  alike.  Each  girt  has  a  three-bolt 
connection  at  each  end. 

E\'ER  Y  l)L\(iONAL  .\L1KE:  Diagonals  are  angles. 
Every  diagonal  member  on  the  tower  is  alike  and 
interchangeable,  and  as  with  the  girts,  each  has  a 
three-bolt  connection. 


nose  board  for  the  elevator  bucket  is  furnished  with 
each  intermediate  section.  Angle  clips  are  provided 
on  the  nose  board  for  attaching  it  to  the  girt  angle.  ' 

All  nose  boards  are  interchangeable. 

ELEVATOR  BUCKET :  The  elevator  bucket  has  36  ‘ 

cu.  ft.  water  level  capacity,  so  designed  that  it  can  ] 

be  reversed  in  its  frame  and  dump  out  of  either  the  i 

front  or  rear  of  the  tower.  The  bail  contains  a  sheave 
for  double  hoisting  line.  Weight  complete  1585  lbs. 

LADDER:  A  pipe  ladder  is  provided  which  can  be  | 

bolted  to  any  one  of  the  four  sides  of  the  tower. 

FRONT  CORNER  POSTS:  The  front  corner  posts  j 

are  composed  of  two  angles  riveted  together  back  to  ^ 

back,  the  outside  angle  acting  as  the  sliding  frame  j 

guide.  The  front  corner  posts  of  the  tower  are  the 
same  from  top  to  bottom. 

RE.\R  CORNER  POSTS:  The  rear  corner  posts  ! 

are  composed  of  one  heavy  angle  and  are  the  same  1 

from  the  top  to  the  bottom  of  the  tower.  The  tower  j 

is  so  designed  that  where  the  plant  requires  it,  double 
angle  legs  such  as  are  used  for  the  front  corner  posts, 
can  be  used  in  the  rear,  greatly  increasing  the  ^ 

strength  of  the  tower,  without  making  a  single  ' 

change  in  any  of  the  other  parts.  This  change  which  ' 

can  be  made  in  the  field  where  conditions  require  it 
makes  it  possible  to  put  a  sliding  frame  plant  on  ) 

both  front  and  rear  of  the  tower;  a  layout  advantage 
which  is  sometimes  very  valuable,  especially  when  j 

considered  in  connection  with  the  reversible  elevator  I 

bucket  which  is  designed  for  use  in  this  tower. 

I 

ELEV.XTOR  BUCKET  GUIDES:  The  elevator 

bucket  guides  consists  of  two  angles,  15  ft.  long, 
gusseted  together  with  angle  clips  for  connection 
to  the  girts.  They  are  interchangeable  from  top  to 
bottom  of  the  tower  and  on  either  side  of  the  tower. 

GUY  CONNECTIONS:  The  intermediate  guy  con¬ 
nections  consist  of  a  set  of  girt  angles,  which  bolt

tain  shackles  for  the  guy  lines  and  can  be  placed  at 
any  panel  point  of  the  tower  to  meet  job  conditions. 
The  top  section  guy  connections  consist  of  heavy 


support  is  so  arranged  that  these  sheaves  may  be

The  unusual  strength  and  rigidity  of  the  Lakewood 
steel  tower  makes  it  possible  to  use  tbe  boom  coun¬

22  and  23).  The  type  of  plant  which  is  used  more 
often  than  any  other  on  general  building  work  is  the 
boom  counterweight  plant.  In  the  past,  steel  towers 
have  been  designed  to  take  the  boom  counterweight 
plant  with  the  provision  that  the  counterweight 
section  must  be  supported  when  pouring  concrete. 


This  feature  in  connection  with  the  boom  coun¬ 
terweight  plant,  eliminates  the  support  for  the 
counterweight  which  in  many  cases  is  very  awkward 
and  troublesome  to  handle.

ing  frame  uses  as  guides,  the  outside  angles  of  the 
front  legs  of  the  tower.  A  short  steel  sliding  frame  is 
provided  for  continuous  and  unit  plant  installations, 
while  a  long  steel  sliding  frame,  including  both  boom 
seat  and  top  line  connection,  is  provided  for  the 
boom  plant.  These  frames  are  so  designed  that  the 
continuous  line  sliding  frame  becomes  the  inter¬ 
mediate  section  of  the  long  steel  sliding  frame,  a 
particularly  valuable  feature,  as  it  cuts  down  the 
number  of  units  required  to  make  up  a  flexible 
chuting  plant  for  the  contractor. 

Sliding  frames  are  provided  with  a  channel  base 
for  the  hopper  operator’s  platform. 

The  sliding  frame,  when  in  position  at  a  panel 
point,  is  fastened  to  the  tower  by  means  of  bolts 


running  thru  slotted  holes  in  the  side  members  of 
the  frame  and  the  outside  angle  of  the  front  legs 
of  the  tower. 

No  dumping  triggers,  aprons  or  baffle  plates  are 
required  for  the  sliding  frame.  A  splash  shield, 
running  around  the  sides  of  the  hopper,  is  furnished 
as  standard  equipment.  Any  size  of  type  “O”  Lake- 
wood  tower  hopper  can  be  used  with  the  standard 
steel  sliding  frames. 

SIDE  PANELS  SHIPPED  ASSEMBLED:  If  desired, 
the  side  panels  of  the  tower  can  be  shipped  com¬ 
pletely  riveted  up,  leaving  as  loose  pieces,  only  the 
front  and  rear  diagonals  and  girts,  which  means 
still  faster  erection.  Towers  will  not  be  shipped  this 
way  unless  specified.

Type  Elevator  Bucket  No*  828-8  For  No.  732  Steel  Tower 

One  of  the  most  unusual  and  valuable  features  of 
the  Lakewood  steel  tower  is  the  elevator  bucket.  This 
bucket  is  so  designed  that  it  is  reversible  and  can  be 
dumped  thru  either  the  front  or  the  rear  of  the  tower. 

The  bucket  is  of  the  nose  board  type,  which  eliminates 
all  triggers,  latches,  springs  and  rollers.  The  result  is 
a  quick  dumping,  smooth  working  bucket  of  the  simplest 
design  possible  and  one  which  requires  a  minimum  of 
attention  under  strenuous  working  conditions. 

The  bucket  body  rides  on  two  rocker  castings,  bolted 
to  its  sides.  These  rocker  castings,  in  turn,  run  on  a 
cast  track  which  bolts  to  the  bottom  of  the  bucket 
frame.  The  bucket  is  positively  locked  into  the  frame 
by  means  of  an  angle  bolted  into  the  upper  part  of  the 
frame  across  the  top  of  the  rocker  castings.  This  angle 
is  slotted  on  the  bottom  so  that  when  the  bucket 
dumps  forward,  the  end  of  the  rocker  casting  will 
catch  in  the  slot,  stopping  the  bucket’s  travel.  When 
returning  from  the  dumping  position,  the  opposite 
end  of  the  rocker  casting  catches  into  this  same  notch, 
thus  limiting  the  bucket’s  backward  travel. 

By  unbolting  the  locking  angles  on  each  side,  the 
bucket  body  can  be  picked  up,  turned  around  and 
headed  to  dump  out  of  the  opposite  face  of  the  tower. 

This  change  can  be  made  in  an  hour,  a  feature  which, 
when  considered  with  the  possibility  of  mounting  a 
sliding  frame  plant  on  both  the  front  and  rear  of  the 
Lakewood  steel  tower,  opens  up  a  new  layout  possi¬ 
bility  never  before  secured  with  standard  equipment. 

The  bucket  weighs  1585  pounds  and  has  a  water  level 
capacity  of  36  cubic  feet.

Long  and  Short  Steel 
Sliding  Frames  for  the 
No.  732  Steel  Tower 


SLIDING  frames  for  steel 
towers  are  constructed  to 
run  on  angle  guides  riveted  to 
the  front  corner  posts  of  the 
tower.  The  frame  is  moved  up 
and  down  the  tower  by  means  of 
a  cable  which  runs  over  sheaves 
on  top  of  the  tower  to  the  hoist¬ 
ing  engine. 

When  the  sliding  frame  is  in 
proper  position  on  the  tower  for 
pouring  concrete,  it  is  fastened 
to  the  tower  by  means  of  bolts 
running  thru  slotted  holes  in  the 
sliding  frame  members  and  the 
guide  angles  on  the  tower.  The 
hoppers  on  the  frame  set  flush 
with  the  tower  and  are  equipped 
with  splash  shields.  No  dumping 
triggers,  aprons  or  latches  are 
required  for  the  elevator  bucket. 
All  steel  sliding  frames  are  equip¬ 
ped  with  channels  which  can  be 
attached  to  either  side  of  the 
frame  to  form  a  base  for  an 
operator’s  platform. 

The  long  steel  sliding  frame 
is  used  for  the  boom  counter¬ 
weight  plants,  but  the  center  or 
hopper  section  of  this  long  slid¬ 
ing  frame  forms  the  short  steel 
sliding  frame  which  is  used  with 
continuous  line  or  straight  unit 
chute  plants.  This  center  sec¬ 
tion  is  complete  in  itself.  For

Long  Steel  Sliding 
Frame  for 
Wood  Towers 


The  Long  Steel  SlidingFrame 
for  a  wood  tower  is  held  in 
place  on  the  tower  by  steel  shoes 
running  on  a  2  x  10  timber, 
bolted  to  the  sides  of  the  front 
corner  posts  of  the  tower.  This 
guide  timber  must,  of  course, 
project  far  enough  out  from  the 
corner  posts  to  allow  the  frame 
to  clear  all  bolt  heads  on  the  face 
of  the  tower.  When  in  position 
for  pouring  the  frame  is  held 
firmly  in  place  on  the  tower  by 
fourteen  clamps  and  in  addition 
should  be  lashed  to  the  corner 
posts.  Any  size  of  Type  “O” 
Hopper  can  be  used  with  this 
frame,  and  the  horizontal  mem¬ 
bers  of  the  frame  are  adjustable 
to  the  widths  of  towers  required 
for  the  Yl,  M.  or  1-yard  Type 
“O”  elevator  byckets. 

The  frame  is  shipped  in  three 
sections  and  can  be  easily  erected 
or  dismantled  in  the  field. 

The  steel  blocks  required  for 
rigging  the  steel  sliding  frames 
are  10"  double.  One  should  be 
fastened  to  the  cat  head  of  the 
tower  and  the  other  to  the  ring 
in  the  top  of  the  sliding  frame. 
The  fall  line  runs  over  sheaves 
on  the  top  of  the  tower  to  the 
hoisting  engine.  Five  eighth  inch 
Plow  Steel  cable  should  be  used 
for  this  purpose.

The  Unit  Plant 

Ideal  For  the  Smaller  Job 

an  area  160  x  90-ft.  where  it  is  possible  to  set  up 
at  the  center  of  the  long  side.  An  80-ft.  unit 
plant  made  up  of  a  50-ft.  boom  section  and  a 
30-ft.  plain  end  section  would  be  ideal — no  sup¬ 
ports  would  be  required  except  at  the  end  of  the 
30-ft.  section  and  the  plant  could  be  handled 
easily  from  point  to  point  when  pouring. 


The  Lakewood  Unit  Plant,  designed  for  use 
on  either  wood  or  steel  towers,  consists  of  a 
tower  hopper  mounted  on  a  sliding  frame,  one 
section  of  trussed  chute,  which  acts  as  a  boom 
and  one  additional  section  of  chute.  This  type 
of  plant  can  be  easily  and  quickly  moved  up  and 
down  the  tower,  and  makes  a  very  compact, 
easily  operated  plant  for  the  smaller  jobs.  The 
unit  plant  is  furnished  in  40,  60,  80  and  100-ft. 
sizes. 

The  essential  differences  between  the  Unit 
Plant  and  the  Boom  Plant  lie  in  the  first  section 
of  chute  and  the  sliding  frames.  In  the  unit 
plant,  the  first  section  of  chute  is  made  heavier 
and  trussed  in  such  fashion  that  no  separate 
boom  is  required.  A  head  line  of  cable  is  run 
from  the  bail  at  the  end  of  the  boom  to  the  cat¬ 
head  of  the  tower,  eliminating  the  steel  boom 
entirely. 

Many  Combinations  Possible 
Many  combinations  can  be  worked  out,  as  any 
size  of  hopper  from  20  to  60  cubic  feet  working 
capacity,  and  any  radius  of  operation  can  be 
secured  with  these  plants,  depending,  of  course, 
on  the  size  of  mixer  used  and  the  area  to  be 
covered  with  the  chutes.  Assume,  for  example. 


It  is  generally  advisable  to  make  up  a  100-ft. 
plant  using  a  50-ft.  boom  section  and  an  addi¬ 
tional  30-ft.  and  20-ft.  elbow  section,  supported 
at  the  30-ft.  point  rather  than  using  two  50-ft. 
sections,  because  the  first  plant  can  be  handled 
so  much  more  easily  than  a  trussed  50-ft.  sec¬ 
tion  and  it  will  cover  the  area  with  fewer  moves 
of  the  entire  plant.  Furthermore,  the  20-ft.  and 
30-ft.  light  counterweight  can  be  attached  to 
the  end  of  the  unit  plant  boom  section  without 
making  any  changes  whatever  in  the  boom  sec¬ 
tion  itself.  In  a  word,  these  smaller  plants  have 
all  the  advantages  of  the  larger  Lakewood  plants, 
but,  being  lighter  and  lower  in  first  cost,  they 
apply  particularly  well  to  the  smaller  jobs.  They 
can  be  assembled  easily  and  quickly  in  the  field 
from  standard  erection  drawings.  When  using 
the  unit  plants  on  a  wood  tower,  we  recommend 
the  standard  Lakewood  wood  tower  design  as 
shown  in  this  bulletin.

Rule  for  Determining 
Tower  Heights 

WHETHER  using  wood  or  steel  towers, 
the  rule  for  determining  the  maximum 
height  of  the  tower  required  is  as  follows: 

Take  the  maximum  height  at  which  concrete 
is  to  be  poured  above  the  tower  base  and  add  to 
this  one-third  of  the  distance  through  which  the 
concrete  is  to  be  chuted,  which  takes  care  of  the 
necessary  fall  in  the  chute  line  and  to  that  sum 
add  20  to  30  feet  for  the  necessary  tower  head- 
room.  The  addition  for  headroom,  of  course 
depends  entirely  upon  the  type  of  plant  used. 


Sizes  of  Timbers  Recommended 
for  Wood  Towers 

The  selection  of  member  sizes  for  a  wood  tower 
will,  of  course,  depend  on  the  tower  height,  guy¬ 
ing  conditions,  and  load  to  be  supported.  For 
lighter  plants,  a  6"  x  6"  corner  post  with  2"  x  6" 
diagonals  and  girts  is  sufficient,  while  for  heavier 
loads,  a  8"  x  8"  corner  post  with  2"  x  8"  cross 
braces  is  recommended.  Bolted  construction 
should  be  used  thruout.  The  tower  details  as 
given  on  the  following  page  are  typical.  Stand¬ 
ard  prints  of  tower  details  will  gladly  be  furnished 
upon  request.

Type  Elevator  Buckets 

Require  Only  Guide  Timbers  for  Operation 


TKE  Type  “L”  Elevator  Bucket  is  a  sturdy 
bucket  of  the  latch  and  trigger  type.  It 
can  be  operated  in  any  shaft  by  simply  instal¬ 
ling  guide  timbers.  This  feature  makes  it  particu¬ 
larly  valuable  on  fireproofing  operations  in  steel 
buildings,  as  many  times  elevator  shafts  are 
available  for  installing  guide  timbers,  thus 
eliminating  the  cost  and  need  of  a  tower.  The 
bucket  is  balanced  to  dump  forward,  but  is  held 
in  the  vertical  or  hoisting  position  by  a  spring 
j  latch  on  the  side  of  the  bucket.  On  dumping,  the 

j  bucket  first  strikes  a  sliding  iron  on  the  tower 

;  hopper  apron,  which  forces  the  bucket  backward, 
relieving  the  load  on  the  latch  at  the  time  it  is 
;  released  by  a  block  on  the  tower  guide,  allowing 
the  bucket  to  dump  into  the  hopper. 

This  type  of  bucket  can  be  used  in  the  stand¬ 
ard  wood  tower  and  is  the  proper  bucket  for  the 
No.  731  Lakewood  Steel  Tower.

Type  ‘‘O”  Elevator  Buckets 

For  Use  With  Wood  Towers 


The  Type  “O”  Elevator  Buckets  are  for 
use  with  wood  towers  only.  They  are  simple 
in  operation,  have  few  working  parts  and  are  as 
light  as  is  consistent  with  good  design.  The 
capacities,  both  working  and  water  level,  are 
given  for  the  various  sizes  on  the  opposite  page. 
The  bucket  is  balanced  to  dump  forward  and  is 
held  in  the  vertical  or  hoisting  position  by  slid¬ 
ing  against  a  nose  board  in  the  face  of  the  tower. 
A  heavy  casting  is  placed  on  the  nose  of  the 
bucket  for  this  purpose.  The  Type  “O”  Bucket 
can  be  made  to  dump  at  any  point  by  removing 
a  section  of  the  nose  board.  In  dumping,  this 
bucket  pivots  about  two  points  and  the  arm 
supporting  the  first  pivot  point  allows  the  bucket 
to  reach  through  the  face  of  the  tower  and  over 
the  tower  receiving  hopper,  attaining  a  45  degree 
discharge  angle.  Sheaves  for  double  hoisting  line 
operation  are  furnished  with  all  buckets.

and  bracket  for  connecting  with  the  elbow  fits 
up  snugly  under  the  discharge  gate  of  the  hop¬ 
per.  This  hopper  is  made  of  12  gauge  steel  for 
the  20  and  30  cubic  foot  capacities  and  of  10 
gauge  steel  for  the  larger  sizes.  The  top  is  rein¬ 
forced  with  2-inch  angles.  The  sides  of  the  hop¬ 
per  are  sloped  to  fit  an  8  x  12  inch  radial  dis¬ 
charge  gate  made  of  sheet  steel  with  malleable 
iron  sides.  This  gate  can  be  operated  from  either 
side  of  the  tower  by  a  lever  with  an  extension 
handle. 

The  width  of  the  hopper  remains  the  same  for 
all  capacities.  The  advantage  of  this  is  that  the 
center  of  gravity  of  the  hopper,  full  or  empty, 
will  be  as  close  to  the  tower  as  possible. 


The  Type  “O”  Tower  Hopper  can  be 
attached  to  the  tower  direct  or  mounted  on 
a  sliding  frame  separate  from  the  tower.  In  wood 
tower  construction  a  2  x  10  must  be  attached  on 
each  side  of  the  front  corner  posts  of  the  tower, 
extending  out  far  enough  in  front  of  the  tower 
to  allow  the  sliding  frame  to  clear  the  bolts  on 
the  cross  braces.  This  provides  a  smooth  track 
for  the  sliding  frame.  With  the  hopper  mounted 
on  a  sliding  frame,  the  unit  can,  of  course,  be 
shifted  to  any  desired  elevation  on  the  tower 
with  the  minimum  amount  of  time  and  labor. 

The  Type  “O”  Tower  Hopper  will  work  with 
any  elevator  bucket  which  will  discharge  outside 
of  the  tower,  but  it  is  made  particularly  for  use 
with  Type  “O”  chute  sections,  as  the  thimble

Chute  Connections 


All  Working  Parts  on  the  Outside  with 
the  Lakewood  Elbow  Connections 

The  elbow  connection  is  used  where  it  is  de¬ 
sired  to  swivel  one  section  about  another. 
The  Lakewood  elbow  connection  is  the  only  type 
which  has  all  working  parts  outside  the  flow  of 
the  concrete,  leaving  an  open  channel  for  the 
concrete  thru  the  elbow.  This  not  only  means 
less  clogging,  but  no  wear  on  parts  used  to  hold 
up  the  chute. 

All  Connections  Bolt  to  Chute,  Can 
Be  Easily  Changed  on  Job 
All  types  of  Lakewood  Chute  Connections  are 
bolted  to  the  chute  flanges.  Any  Lakewood 
Chute  connection  can  be  attached  to  any  Lake- 
wood  Chute  Section.  This  means  complete  inter¬ 
changeability  of  Lakewood  Chute  parts  on  the 
job  and  makes  it  possible  for  the  contractor  to 
change  his  chute  sections  from  swivel  head  to 
continuous  line  or  vice  versa  to  meet  job  con¬ 
ditions. 


The  No.  2  elbow  is  attached  at  the  discharge 
end  of  the  chute.  A  loose  trunnion  ring  of  cast 
steel  with  two  heavy  lugs  rests  upon  a  cast  steel 
flange,  bolted  to  the  lower  end  of  the  elbow. 
This  trunnion  ring  has  a  full  circle  swing.  The 
No.  3  elbow  is  attached  at  the  receiving  end  of 
the  chute.  The  top  is  reinforced  with  steel  bar 
Two  angle  ears  are  riveted  opposite  each  other 
and  on  the  outside  of  the  elbow.  These  ears 
pass  up  on  each  side  of  the  lugs  in  the  trunnion 
of  the  No.  2  elbow  and  a  bolt  passed  through 
them  over  the  lug,  which  makes  the  connection 
between  the  two  sections  of  chute.  On  account 
of  the  two  point  support  there  is  no  chance  for 
the  chute  to  tip  sideways  and  spill  the  concrete. 
The  full  circle  action  is  obtained  in  the  trunnion 
ring  and  vertical  movement  through  the  bolt 
riding  on  the  trunnion  lugs.  All  working  parts 
are  on  the  outside,  leaving  the  inside  free  and 
open.  There  is  no  possibility  of  the  concrete 
clogging.  The  elbows  are  full  circle  section  and 
have  twice  the  capacity  of  the  chute  itself.

Continuous  Line  Chute  Joints 
Simple  and  Safe 


CONTINUOUS  line  chute  which  is 
suspended  from  an  overhead  cable 
must  have  flexible  joints  at  least  every 
30-ft.  to  compensate  for  the  sag  of  the 
cable  and  swing  of  the  chute  line.  This 
joint  is  known  as  the  No.  6  and 
attaches  to  the  discharge  end  of  the 
chute.  It  consists  of  an  apron  and 
flange.  The  apron  rests  on  the  receiv¬ 
ing  end  of  the  following  chute  and  the 
two  sections  are  tied  together  by  means 
of  2%  X  bolts  and  two  hangers  as 
shown  on  page  45.  The  bolts  are  left 
loose  to  permit  movement.  Attach¬ 
ment  can  be  made  quickly  and  easily 
in  the  field  to  any  Lakewood  Chute.

Two  Types  of  Swivel  Connections 
Available  with  Lakewood  Chute 

WHEN  Lakewood  chuting  equipment 
was  first  developed,  the  type  of 
chute  connection  used  was  similar  to  that 
shown  on  the  right.  The  No.  5  apron  is 
attached  at  the  discharge  end  of  the  chute 
section ;  heavy  bolt  hook  passes  thru  it  and 
swivels  on  cross  angles  at  the  top  of  the 
apron.  This  apron  deflects  the  concrete 
into  the  square  hopper  of  the  following 
chute  section.  The  No.  4  square  hopper 
is  attached  to  the  receiving  end  of  the 
chute  section.  A  standard  chute  hanger, 
located  about  midway  of  the  hopper,  rests 
in  the  hook  of  the  apron.  Vertical  move¬ 
ment  is  obtained  with  the  rocking  of  the 
hanger  in  the  hook  and  full  circle  swing  in 
the  swiveling  of  the  hook.  This  type  of 
connection  has  been  largely  replaced  by 
the  Type  “O”  Lakewood  chute  connection, 
but  it  can  be  used  with  any  Lakewood 
Chute  section.

40%  Greater  Wearing  Thickness 
in  Lakewood  Chute 

The  Lakewood  Chute  Section  is  14"  wide 
and  deep.  The  body  plate  of  all  sec¬ 

tions  is  12  gauge  plate,  giving  40%  greater  wear¬ 
ing  thickness  than  14  gauge  plate.  All  Lake- 
wood  chute  flanges  are  of  annealed  cast  steel 
and  jig  drilled,  giving  strength  and  accuracy. 

Standard  sections  are  built  in  10'  and  20' 
lengths.  From  those  standards,  30',  40'  and  50' 
chutes  are  built  up.  A  30'  chute  is  the  longest 
without  trussing. 


Complete  Interchangeability 
of  Parts 

ALL  Lakewood  Chute  Sections  are  inter- 
changeable.  Any  Lakewood  elbow,  hop¬ 
per  or  flexible  joint  can  be  attached  to  any  chute 
section.  Standard  struts  or  plates  for  truss  rods 
can  be  used  on  any  standard  section  of  chute. 
This  complete  interchangeability  means  greater 
value  to  the  user  as  he  has  equipment  which  can 
be  varied  without  difficulty  on  the  job  to  meet 
conditions.

Continuous  Line  Chutes 


The  Lakewood  continuous  line  chutes  are 
made  in  lengths  of  ten,  twenty  and  thirty 
feet,  with  a  No.  6  joint  at  the  discharge  end.  No 
connection  is  required  at  the  receiving  end  as 
indicated  by  the  “zero”  for  the  third  figure  in 
the  section  numbers. 

When  strung  up  on  a  cable.  No.  6  flexible 
joints  should  be  installed  every  twenty  or  thirty 
feet  to  compensate  for  the  sag  and  swinging  of 
the  supporting  cable. 

Each  No.  6  joint  includes  two  hangers  as¬ 
sembled  as  shown  on  the  opposite  page.  From 
these  hangers,  blocks  and  rope  make  connection 
with  the  overhead  cable. 

Two-Way  Switch 

Wherever  it  is  necessary  to  distribute  con¬ 
crete  in  two  directions  from  the  tower  hopper, 
using  continuous  line  chute  a  Type  “O”  two- 
way  hopper  switch  is  required. 


This  switch  can  be  suspended  directly  from 
the  thimble  and  bracket  under  the  tower  hopper 
and  provides  for  the  take-off  of  two  chute  lines 
at  its  base.  A  flap  valve  controls  the  direction 
of  flow  of  concrete  thru  the  switch. 

Line  Gates 

If  concrete  is  to  be  distributed  at  two  or  more 
points  from  the  same  continuous  line  chute,  a 
line  gate,  as  shown  on  the  opposite  page,  must 
be  placed  in  the  line.  Additional  chute  can  be 
attached  to  the  line  gate  or  a  flexible  chute  hop¬ 
per  can  be  attached  and  the  concrete  dropped 
to  the  forms.  This  line  gate  is  built  into  the  cen¬ 
ter  of  a  10  ft.  standard  Chute.  To  the  bottom  is 
fastened  a  standard  trunnion  ring  for  attaching  an 
elbow  or  a  round  flexible  chute  hopper,  as  the  case 
may  be.  It  is  necessary  when  using  a  line  gate  to 
support  it  to  the  overhead  cable  from  both  ends. 
Hangers  are  provided  for  this  purpose  and  a  No. 
6  chute  connection  is  always  included.

Unit  Boom  Chute  Sections 

Lakewood  boom  chute  sections  are  the 
^first  sections  of  chute  in  the  unit  or  unit- 
counterweight  plants.  They  are  designed  for 
greater  strength  than  the  standard  trussed  sec¬ 
tions,  the  trussing  and  size  of  angle  on  the  chute 
being  considerably  heavier.  These  boom  chute 
sections  are  made  in  20,  30,  40  and  50  foot 
lengths  for  use  with  the  various  sizes  of  plants. 

When  used  with  unit  plants,  or  with  plants 
using  a  CL-2030,  or  CL-3030  counterweight, 
the  receiving  elbow  of  the  boom  section  is  a  3-R 
and  the  discharge  elbow  a  plain  No.  2.  When 
used  with  the  heavier  30  or  50  foot  counter¬ 
weights,  the  receiving  elbow  is  a  3-H  and  the 
discharge  elbow  a  2-H.  These  various  elbows 
are  consistent  in  strength  to  the  type  of  plant 
with  which  they  are  to  be  used. 


Counterweight  Chute  Sections 
To  provide  great  range  in  the  size  of  counter¬ 
weight  plants,  Lakewood  counterweight  chutes 
are  made  in  20,  30  and  50  foot  sizes,  and  in  two 
types,  heavy  and  light.  There  are  special  appli¬ 
cations  for  each  type,  which  will  be  briefly 
outlined. 

The  CL-2030  and  CL-3030  chutes  are  counter 
balanced  distributing  chutes.  By  means  of  the 
bracket  which  can  be  attached  to  any  standard 
20  or  30  foot  section,  the  chute  may  be  counter¬ 
balanced  for  its  own  weight  empty  When  pour¬ 
ing,  or  when  additional  sections  are  attached  to 
it,  the  CL-2030,  or  CL-3030  must  always  be 
supported  at  the  discharge  end.

The  C-3030  is  a  heavy  type  30-ft.  counter¬ 
weight.  When  used  on  a  steel  tower,  with 
any  type  of  plant,  it  may  be  tied  down  when 
pouring,  if  used  alone  or  with  a  30-ft.  chute 
attached,  or  it  may  be  counterweighted  to  support 
as  much  as  a  50-ft.  section  when  not  pouring; 
but,  in  a  tied  down  condition,  either  on  a  boom, 
unit  or  continuous  line  plant,  it  must  not  have 
a  greater  load  than  one  thirty  foot  length  of 
chute. 

The  CL-5030  counterweight  should  never  be 
tied  down  under  any  circumstances  when  pour¬ 
ing,  on  either  wood  or  steel  towers.  It  can  be 
counterweighted  enough  to  support  an  addi¬ 
tional  50-ft.  section  when  empty,  but  should 
always  be  supported  at  the  discharge  end  when 
pouring  concrete. 

The  C-5030  is  designed  principally  for  use  in 
continuous  line  or  mast  hopper  plants  where 
it  is  supported  by  a  derrick.  However,  with  a 
boom  counterweight  plant  on  a  steel  tower  of 
the  No.  732  type,  it  may  be  used  tied  down, 
supporting  an  additional  30-ft.  chute  when 
pouring  concrete. 


The  HC-5032  or  extra  heavy  counterweight 
is  designed  only  for  double  counterweight  plant 
installations  on  continuous  line  or  derrick  sup¬ 
ported  plants.  It  may  be  tied  down  supporting 
a  CL-5032  when  pouring  concrete,  but  the  dis¬ 
charge  end  of  the  light  50-ft.  counterweight  must 
be  supported,  when  pouring,  for  it  never  is  to  be 
tied  down  under  any  circumstances.  This  sec¬ 
tion  is  not  to  be  used  with  boom  or  unit  plants. 

Counterweight  chutes  are  made  up  of  stand¬ 
ard  chute  sections  with  truss  or  bracket  attached, 
depending  on  the  size.  Complete  tables  are  given

The  Lakewood  Concrete  Cart  has  a  capacity 
of  6  cubic  feet  of  material  and  can  be  fur¬ 
nished  with  or  without  legs  as  desired.  The  bot¬ 
tom  and  sides  of  the  cart  are  constructed  of  one- 
eight  inch  plate.  The  axles  are  pressed  into  star 
shaped  malleable  iron  trunnions  which  are  bolted 
to  the  side  of  the  cart,  adding  strength  and  re¬ 
ducing  the  chance  of  bent  axles.  The  elimina¬ 


tion  of  the  long  axle  through  the' body  makes 
possible  complete  and  unobstructed  discharge. 
Large  diameter  wheels  with  wide  tread  permits 
easier  travel  over  rough  surfaces.  The  Lake- 
wood  concrete  cart  was  designed  for  maximum 
strength  with  minimum  weight  and  absolutely 
meets  the  requirements  of  the  job.  42"  diam¬ 
eter  wheels  are  standard.

Type  Tower  Hoppers 

For  Use  with  Concrete  Carts  Only 


The  Lakewood  Type  “M”  Tower  Hopper 
was  designed  primarily  for  use  on  jobs 
where  the  concrete  is  to  be  distributed  by  con¬ 
crete  carts.  The  point  of  discharge  is  well  away 
from  the  tower,  thus  allowing  ample  clearance 
for  the  carts  when  loading.  These  hoppers,  in 
the  20  and  30  cubic  foot  sizes,  are  made  of  12 
gauge  plate,  while  the  40  and  60  foot  sizes  are 
of  10  gauge  plate.  They  are  all  equipped  with 
an  8"  X  12"  radial  gate. 

It  is  impossible  to  connect  chutes  to  this  type 
of  tower  hopper.  However,  it  may  be  mounted 
on  a  Number  500  wood  sliding  frame  if  desired, 
or  may  be  attached  to  the  tower  as  shown  in  the 
sketches  below. 

This  hopper  can  be  made  into  a  floor  hopper 
simply  by  the  addition  of  standards,  or  it  may 
be  used  as  a  charging  hopper  for  elevator  buck¬ 
ets  in  re-elevating  towers,  on  large  chuting  plants.

Floor  Hoppers 


The  Lakewood  Floor  Hopper  is  especially 
designed  for  holding  concrete  which  is  to  be 
distributed  with  carts  or  wheelbarrows.  It  is 
portable,  self-supporting  and  may  be  placed  in 
any  convenient  location.  It  consists  of  a  Type 
“M”  tower  hopper,  bolted  to  steel  standards. 
This  construction  makes  it  easy  to  erect  or 
dismantle  in  the  field,  and  allows  the  body  to  be 
used  as  a  tower  hopper  if  desired.  The  discharge 
gate  of  the  Hopper  extends  out  so  that  there  is 
ample  of  clearance  for  charging  carts  or  wheel¬ 
barrows  as  the  case  may  be.

Tower  Sheaves 

Top  Sheaves 

Lakewood  hoist  line  sheaves  are  all  of 
J  cast  steel  and  can  be  equipped  with  bear¬ 
ing  boxes  to  suit  the  load  and  speed  conditions. 
Standard  top  sheaves  have  a  fixed  pin  and  run 
in  bronze  bushed  boxes,  but  can  be  equipped 
with  Hyatt  Roller  Bearing  Boxes  for  high  speed 
work. 

Bearings  for  High  Speed  Hoisting 

Where  unusually  high  speed  hoisting  is  to  be 
done,  we  recommend  the  use  of  large  diameter 
sheaves  equipped  with  Special  Hyatt  roller 
bearing  boxes  as  shown  to  the  left.  Either  cast 
steel  or  manganese  steel  sheaves  can  be  pro¬ 
vided. 

Lakewood  bottom  swivel  sheaves  are  bronze 
bushed  and  run  on  a  fixed  pin  which,  in  turn, 
is  mounted  on  a  heavy  steel  swivel  bracket. 
If  desired,  Hyatt  Roller  Bearings  can  be  fur¬ 
nished  in  the  hub  of  bottom  sheaves.  Details 
and  weights  are  given  in  the  table  below:

Flexible  Chutes 


Flexible  chutes  can  be  used  to  advantage  for 
guiding  the  flow  of  concrete  in  vertical  or 
nearly  vertical  lines.  The  connecting  chains 
allow  the  twisting  of  sections  and  make  it  pos¬ 
sible  to  lead  the  chute  about  in  a  circle,  similar 
to  the  action  of  an  elephant’s  trunk;  for  this 
reason,  they  are  sometimes  called  elephant 
trunk  chutes. 

The  elephant  trunk  sections  are  made  in  3' 
and  4'  lengths  and  are  tapered  so  that  the  small 


end  of  one  tube  fits  loosely  into  the  large  end  of 
the  next  section,  giving  the  necessary  working 
clearance. 

The  hoppers  to  which  these  chute  sections  are 
attached,  are  made  either  round  or  square  and 
can  receive  concrete  from  mixers,  cars,  carts, 
ends  of  the  chute  lines  or  line  gates.  The  round 
hopper.  No.  8850,  has  angle  lugs  on  it  so  that  it 
can  be  easily  attached  to  the  standard  Type  “O” 
elbow  or  line  gate.

material  bins,  hoppers  or  bulk  heads,  where  loose 
material,  such  as  sand,  stone,  gravel,  ore,  coal 
or  concrete  is  to  be  discharged.  These  bins  are 
made  in  two  standard  styles  and  sizes,  of 
steel  plate  reinforced  with  malleable  iron  cast¬ 
ings.  The  maximum  size  of  aggregate  that  will 
flow  freely  through  the  12"  x  18"  gate,  is  one 
that  will  pass  through  a  7"  ring;  the  maximum 
size  of  aggregate  that  will  flow  through  an  18"  x- 
18"  gate  freely,  is  one  that  will  pass  through  a 
9"  ring.  The  gate  proper  fits  snugly  against  the 
side  and  end  plates.  Special  care  has  been  taken 
in  its  construction  to  make  them  practically 
grout  tight.

Occasions  arise  in  construction  work  where 
concrete  can  be  most  advantageously  han¬ 
dled  by  the  use  of  cars.  The  above  photograph 
shows  a  combination  of  chuting  and  cars.  The 
concrete  was  chuted  to  a  centrally  located  hop¬ 
per  from  which  it  was  taken  by  means  of  radial 
gate  hopper  cars  to  the  forms. 

The  Lakewood  Radial  Gate  Hopper  car  shown 
above,  has  been  designed  to  solve  just  such 
problems.  The  frame  is  of  heavy  channel  con¬ 
struction  and  the  wheels  are  cast  iron  with 
chilled  tread,  12"  in  diameter  running  on  1'^” 
axles  with  plain  roller  bearings.  Altho  not  shown 
in  the  cut,  link  and  pin  couplers  are  provided 
as  standard  equipment. 

This  car  is  not  only  useful  for  handling  con¬ 
crete,  but  can  also  be  used  to  good  advantage 


to  carry  chemicals,  coal,  and  other  fine  material. 
All  dimensions  are  given  in  the  table  below.

Concrete  Mixers 


The  Mixers  With  the  Worm

NO  mixer  ever  equalled  the  gear 
driven  Lakewoods  for  husky 
build  and  years  of  service. 

Now,  with  the  worm  speed  reduc¬ 
tion,  Lakewood  has  given  to  users  of 
building  mixers,  new  advantages  in 
operation  and  maintenance,  with  the 
same  sturdiness  which  made  the  old 
gear  driven  Lakewood  mixers  famous 
thruout  the  world. 

Lakewood  Mixers  conform  to  the 
A.  G.  C.  standards  in  all  respects  and 
are  built  in  ]/l,  3^,  1  and  2-yd.

The  Material  Hoist  Tower 


The  Lakewood  Material  Tower  is  a  tower 
of  steel  construction  for  the  hoisting  of  all 
miscellaneous  materials  entering  into  construc¬ 
tion  work.  The  tower  is  equipped  with  a  7x7 
platform  cage,  having  a  live  load  capacity  of 
2500  lbs.  Towers  can  be  built  up  to  300-ft.  in 
height  using  standard  intermediate  sections.  As 
the  tower  is  square  in  cross  section  all  girts  are 
alike,  all  diagonals  are  alike  and  all  corner  posts 
are  alike. 

Quantity  production  makes  possible  especially 
attractive  prices.  The  tower  can  be  used  on  job 
after  job  if  given  average  care  —can  be  stored  in 


a  remarkably  small  space — has  interchangeabil¬ 
ity  of  parts  worked  out  to  a  maximum,  so  that 
it  can  be  easily  and  quickly  erected  or  dis¬ 
mantled — gives  uniform  strength — and  not  only 
handles  material  in  carts  or  wheelbarrows  but 
can  be  equipped  with  a  bucket  and  hopper  for 
handling  concrete  if  desired. 

It  is  interesting  to  note  that  few  contractors 
ever  return  to  wood  material  hoist  towers  after 
once  using  the  steel  tower  for  that  purpose. 
Lakewood  bulletin  No.  25  gives  complete  de 
tails.  A  copy  will  gladly  be  sent  upon  request.

The  Mast  Plant 


The  H.  E.  Culbertson  Co.  of  Cleveland  own  this 
mast  plant  which  is  shown  in  use  on  railroad  bridge 
construction 


The  Mast  Plant  is  a  concrete  placing  plant 
for  the  smaller  job.  Readily  applicable  to 
concrete  construction  such  as  schools,  silos, 
garages,  retaining  walls  and  smaller  concrete 
bridges,  it  has  been  found  to  produce  real  sav¬ 
ings  on  jobs  running  as  low  as  300-yds.  and  as 
high  as  2-3000  cu.  yds.  of  concrete. 

The  cost  of  a  mast  plant  is  low.  Erection  is 
easy.  Its  operation  is  simple  and  economical. 

The  cost  of  a  wood  tower  plant  which  will  do 
what  a  mast  plant  will  do,  will  almost  equal  the 
first  cost  of  a  mast  plant  itself.  The  steel  mast 
plant  is  good  for  twenty  jobs  and  more,  given 
average  care;  while  a  wood  tower  is  generally 
a  one  job  proposition. 

The  mast  will  hoist  all  the  miscellaneous 
materials  as  well  as  the  concrete,  as  it  can  be 
equipped  with  a  material  elevator  platform  which 
will  work  on  one  side  of  the  mast,  at  the  same 
time  concrete  is  being  hoisted  in  the  bucket  on 
the  opposite  side  Thus  a  separate  material 


elevator  cage  and  tower  are  eliminated  by  the 
mast  plant. 


Bulletin  24-A  gives  all  the  de¬ 
tails  on  the  Lakewood  Mast 
Chuting  Plants.

Capacity  of  cable  varies  directly  as  sag — i.  e.  12%  sag  increases  capacity  50%  over  8%  sag.  Stress  due  to  the  weight 
of  cable  itself  has  been  considered  in  compiling  these  tables. 

Factor  of  Safety  5. 

EXAMPLE 

Assume  chute  line  280  feet  long  with  one  line  gate  with  ninety  feet  of  chute  attached  to  it.  Distance  between  tail 
tower  and  main  tower  380  feet.  Assume  ^-yard  mixer  being  used.  Maximum  possible  live  load  two  21  cu.  ft.  batches 
concrete  in  this  case. 

Under  no  circumstances  figure  live  load  more  than  50  lb.  per  lineal  foot. 

Deadload-weight  of  Lakewood  continuous  line  chutes  including  rope  and  blocks  may  be  taken  as  22  lbs.  per  lineal  foot. 
Weight  of  chute  on  line  gate  should  be  doubled  when  figuring  size  of  cable. 

Computations — 

6,160  lbs.  weight  of  chute  line. 

350  lbs.  weight  of  line  gate. 

4,060  lbs.  weight  of  chutes  on  line  gate. 

10,570 
6,300 

=  16,870  lbs. 


Dead  load  280x22
